Researchers reveal how gut microbes shape metabolic strategies to fuel larger brains, offering a glimpse into the evolutionary biology of primates. Putative model for microbial influences on the ...

Longer thumbs mean bigger brains, scientists have found—revealing how human hands and minds evolved together. Researchers studied 94 different primate species, including fossils and living animals, to ...

Humans take nearly 18 to 25 years to reach full maturity, far longer than most mammals. This slow human growth is driven by ...

The human brain is three times bigger than a chimp's and more spherical than a Neanderthal's. Within a maze of bumps and grooves, neurons converse in distinct patterns that give humans unique ...

Humans, who are classified among the five great apes, are closest genetically, i.e., DNA similarity, to chimpanzees (98.8%-99%) and bonobos (98.8%). [Blueringmedia ...

The large, capable human brain is a marvel of evolution, but how it evolved from a smaller primate brain into the creative, complex organ of today is a mystery. Scientists can pinpoint 'when' our ...

A new study reveals that changes to the gut microbiome can change the way the brain works. Subscribe to our newsletter for the latest sci-tech news updates. Humans have the largest relative brain size ...

Modern humans, Neanderthals, and other recent relatives on our human family tree evolved bigger brains much more rapidly than earlier species, a new study of human brain evolution has found. The study ...

The largest animals do not have proportionally bigger brains -- with humans bucking this trend -- a new study has revealed. The largest animals do not have proportionally bigger brains -- with humans ...

Could social bonds be the key to human big brains? A study of the fossil teeth of early Homo from Georgia dating back 1.77 million years reveals a prolonged childhood despite a small brain and an ...

The axolotl may look cartoonishly harmless, but beneath its frilly gills lies one of evolution’s most astonishing survival abilities: functional brain regeneration.
